Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design;

FIG. 2 is a front elevation view thereof; the top and bottom views thereof are identical to the front elevation view.

FIG. 3 is a rear elevation view thereof;

FIG. 4 is a left side view thereof; the right side view thereof is a mirror image of the left side view; and,

FIG. 5 is a detail view of the area from upper 5-5 to lower 5-5 in FIG. 2 .

In the drawings, the evenly spaced broken lines defining the sidewall, inner bead depict subject matter that forms no part of the claimed design. The dash-dot-dash broken lines, which are unclaimed, form the peripheral boundary between the claimed tire tread and the unclaimed sidewall. 

CLAIM The ornamental design for a tire tread, as shown and described.
